  • the present invention relates to an opening action supporting device that supports the opening action of a door body, and relates to an opening section device that includes the opening action supporting device.
  • a configuration is disclosed that includes an opening action supporting mechanism which, when an operation handle disposed in a vertical stile of a sliding door is turned, simultaneously kicks the sliding door against the frame member and relieves the force required for opening the sliding door.
  • the present invention is made in view of the issues faced in the conventional technology, and it is an object to provide an opening action supporting device that enables achieving enhancement in the operability and achieving enhancement in the general versatility of an operation mechanism and an opening action supporting mechanism, and to provide an opening section device that includes the opening action supporting device.
  • An opening action supporting device includes an opening action supporting mechanism including a kicking member that is projectable and retractable from an outer face of a door body, the opening action supporting mechanism being configured to press a frame member supporting the door body that is openable and closable with respect to the frame member, by using the kicking member, to kick the door body against the frame member at time of opening the door body.
  • An operation mechanism provided in the door body is linked to the opening action supporting mechanism via an interlocking member so that, when the operation mechanism is operated, the opening action supporting mechanism operates.
  • the opening action supporting device includes a clutch mechanism configured to connect the interlocking member to the opening action supporting mechanism, and the clutch mechanism is configured to: connect the interlocking member, which moves in one direction when the operation mechanism is operated to a predetermined operating position in an opening direction, to the opening action supporting mechanism to transmit movement of the interlocking member to the opening action supporting mechanism to move the kicking member from a housing position at which the kicking member is retracted inside the door body to a kicking position at which the kicking member is projected outside the door body; and disconnect the interlocking member, which further moves in the one direction when the operation mechanism is further operated from the predetermined operating position in the opening direction, from the opening action supporting mechanism not to transmit movement of the interlocking member to the kicking member.
  • An opening section device includes: the opening action supporting device including the above-described configuration; the door body that is supported by the frame member to be openable and closable with respect to the frame member and that is provided with the opening action supporting device; the operation mechanism that includes an operating unit exposed on an outer face of the door body; and the interlocking member that is movably supported inside the door body.
  • the user at the time of opening the door body, the user only has to operate the operation mechanism to the maximum operation position beyond a predetermined operation position, so that the clutch mechanism changes from the connected state to the disconnected state, and the locking member can be housed after the door body has been kicked.
  • the user after the door body is kicked using the kicking member, the user can open the door body using the operation mechanism that has been operated to the maximum operation position, thereby enabling achieving a high degree of operability.
  • the opening action supporting device as a result of including the clutch mechanism, the separately-designed opening action supporting mechanism can be easily combined with the operation mechanism and the interlocking member. For that reason, the operation mechanism need not be configured on the premise of installation of the opening action supporting mechanism.
  • the opening section device depending on the specifications of the opening section device, it becomes possible to install a plurality of opening action supporting mechanisms or it becomes possible to select the presence or absence of opening action supporting mechanisms using the same operation mechanism and the same interlocking member. That enables achieving a high degree of general versatility.
  • the clutch mechanism can include a unidirectional transmission structure that disconnects the interlocking member, which moves in another direction that is an opposite direction of the one direction when the operation mechanism is operated in a closing direction, from the opening action supporting mechanism.
  • the opening action supporting mechanism can include a first elastic member configured to bias the kicking member in a direction in which the kicking member moves from the kicking position to the housing position.
  • the kicking member In a state where the interlocking member that moves in the one direction is connected to the opening action supporting mechanism by the clutch mechanism, the kicking member can move to the kicking position against biasing force of the first elastic member, and in a state where the interlocking member that moves in the other direction that is an opposite direction of the one direction is disconnected from the opening action supporting mechanism by the clutch mechanism, the kicking member can move to the housing position due to biasing force of the first elastic member.
  • the kicking member after having kicked the door body, the kicking member can be reliably moved to the housing position using the biasing force of the first elastic member.

  • the clutch mechanism can be configured with a simple configuration using the pin member and the guiding holes, and the structure of the opening action supporting device can be simplified. Moreover, by varying the angle, the length, and the arrangement of the first guiding portion and the tilted second guiding portion, replacing the member having the first guiding portion and the second guiding portion enables kicking at an arbitrary operation position. That enables achieving a high degree of general versatility at low cost.
  • the kicking member can include a first arm one end portion of which is rotatably positioned and supported with respect to the door body, a second arm one end portion of which is rotatably linked to another end portion of the first arm and another end portion of which is provided with the pin member, and a roller that is provided in a linking portion for linking the first arm and the second arm, and when the pin member is pressed by the driving face of the driving member, the first arm and the second arm are folded with the linking portion serving as fulcrum, so that the roller protrudes from the door body to press the frame member.

At that time, since the fixed axle 70 is inserted in the long hole 41c, the sliding of the coupling member 41 is not blocked by the fixed axle 70.
  • the driving member 58 is supported in a turnable manner on the inner periphery side of the driving member housing portion 41d of the coupling member 41, and passes through the opening 40b of the interlocking lever 40.
  • the driving member 58 includes a driving face 58a that enables lifting of the driving pin 60; a flank face 58b that extends downward in a substantial orthogonal manner from the driving face 58a; a shaft hole 58c in which a turn shaft 82 is fit by insertion in a rotatable manner; and a stopper piece 58d that protrudes from below the shaft hole 58c toward the inner face of the coupling member 41.
  • the driving member 58 has the shape of a bottomed vessel with an inner space in which a torsion coil spring (a second elastic member) 84 is disposed.
  • the torsion coil spring 84 is extrapolated on the turn shaft 82.
  • the leading end of the stopper piece 58d is set at a turning position in an abutting manner against the inner face of the driving member housing portion 41d due to the biasing force of the torsion coil spring 84 (see FIG. 5(A) ).
  • the driving member 58 is retained in a tilted orientation in which the driving face 58a gradually tilts upward to the side of the vertical frame 14d, and the flank face 58b gradually tilts downward to the side of the vertical frame 14d. At that time, the driving face 58a is positioned at an overlapping position below the driving pin 60.
  • the guiding holes 62 are formed in the bent pieces 50d of the base portion 50, and are positioned facing each other in a pair.
  • the guiding holes 62 are substantially boomerang-shaped long holes having a first guiding portion 62a running along the vertical direction, and having a second guiding portion 62b that is continuous from the upper end of the first guiding portion 62a and that is tilted upward in the direction of gradually moving away from the side of the driving member 58.
  • the driving pin 60 gets inserted in a slidable manner.
  • the guiding holes 62 can vary the position of the driving pin 60 along the width direction (the X direction) of the vertical stile 12d.
  • the driving pin 60 is positioned at the lower end of the first guiding portions 62a of the guiding holes 62; the first arms 66 and the second arms 67 are aligned substantially along the vertical direction, and the kicking member 48 is positioned at a housing position at which the roller 69 is retracted inside the vertical stile 12d.
  • the driving face 58a of the driving member 58 is positioned sufficiently away from the driving pin 60.
  • the operation handle 29 is turned in the opening direction.
  • the interlocking member 32 moves up and, at the 89° position, lifting of the driving pin 60 is started due to the driving face 58a of the driving member 58 (see FIG. 5(B) ). That is, from the 0° position to the 89° position, the clutch mechanism 28 is in the disconnected state and the driving member 58 is positioned away from the driving pin 60.
  • the opening action supporting mechanism 26 (the kicking member 48) does not operate.
  • the drawing member 42 moves up accompanying the interlocking member 32 even from the 0° position to the 89° position.
  • the drawing piece 42a moves relatively upward with respect to the head portion 44a of the lock pin 44 (see FIGS. 5(A) and 5(B) ).
  • the lock pin 44 gets entirely disposed in the lock opening 42c at a 96° position.
  • the lock mechanism 22 gets unlocked.
  • the opening section device 11 during the operation of unlocking the lock mechanism 22 from the locked state, the opening action supporting mechanism 26 does not operate in principle. For that reason, a defect in which the sliding door 12 is kicked before the unlocking of the lock mechanism 22 can be prevented from occurring.
  • the roller 69 presses the inside depth face 47 of the vertical frame 14d (see FIG. 6(A) ), and the sliding door 12 slides to the open position due to the pressing force.
  • the operation handle 29 is positioned at the 145° position
  • the amount of protrusion of the roller 69 reaches the maximum level (kicking position). That is, at the 145° position, the amount of kicking the sliding door 12 by the kicking member 48 reaches the maximum level, and the action of kicking the sliding door 12 by the kicking member 48 reaches completion (see FIG. 6(A) ).
  • the driving pin 60 moves inside the guiding holes 62 from the first guiding portion 62a to the second guiding portion 62b. Then, while rising up in the second guiding portion 62b, the driving pin 60 also gradually moves in the direction away from the driving face 58a of the driving member 58.
  • the driving pin 60 is positioned at the end portion of the driving face 58a, that is, at the boundary between the driving face 58a and the flank face 58b.
  • the amount of tensile force of the extension coil spring 74 also reaches the maximum level, that is, the biasing force for pressing the driving pin 60 downward also reaches the maximum level.
  • the driving pin 60 slips off to the flank face 58b from the driving face 58a due to the biasing force of the extension coil spring 74, and moves down inside the guiding holes 62 while sliding on the flank face 58b (see FIG. 6(B) ).
  • the driving pin 60 moves to the lower end of the first guiding portion 62a, that is, to the position same as the 0° position.
  • the interlocked state between the driving pin 60 and the driving face 58a of the driving member 58 is disconnected, and the clutch mechanism 28 becomes disconnected.
  • the kicking member 48 While the driving pin 60 moves down inside the guiding holes 62, the kicking member 48 is gradually released from the folded state of the first arms 66 and the second arms 67 because of the downward movement of the second arms 67 (see FIG. 6(B) ). As a result, the kicking member 48 is gradually housed in the vertical stile 12d, and the movement of the driving pin 60 to the lower end inside the guiding holes 62 results in the return of the kicking member 48 to the housing position same as the 0° position.
  • the opening section device 11 includes the opening action supporting mechanism 26 that operates in conjunction with the turning of the operation handle 29 in the opening direction.
  • the opening section device 11 includes the clutch mechanism 28 that is capable of connecting the interlocking member 32 and the opening action supporting mechanism 26 in the midway of the action of turning the operation handle 29 in the opening direction.
  • the user only needs to turn the operation handle 29 to a predetermined angular position (a predetermined operation position; in the present embodiment, the 145° position) and then directly turn the operation handle 29 to the turning end position (in the present embodiment, the 180° position).
  • the clutch mechanism 28 changes from the disconnected state to the connected state and the opening action supporting mechanism 26 operates; and then the clutch mechanism 28 changes to the disconnected state and the opening action supporting mechanism 26 gets disconnected from the interlocking member 32.
  • the housing mechanism portion 52 in which the extension coil spring 74 is used the kicking member 48 that has been disconnected from the interlocking member 32 after the completion of the kicking action can be automatically housed at the housing position same as the 0° position. Meanwhile, the housing mechanism portion 52 can be omitted as well.
  • the clutch mechanism 28 when the clutch mechanism 28 is disconnected at the 145° position, the driving pin 60 moves down due to its own weight.
  • the kicking member 48 can be automatically housed at the housing position after the completion of the kicking action.
  • the kicking member 48 is again housed after having kicked the sliding door 12.
  • the user can easily open the sliding door 12, thereby enabling achieving a high degree of operability.
  • the kicking member 48 does not obstruct the passage.
  • the opening section device 11 since the opening section device 11 includes the clutch mechanism 28; the opening action supporting mechanism 26 that is separately designed can be easily combined with the operation mechanism 24 and the interlocking member 32. Hence, the operation mechanism 24 need not be configured on the premise of installing the opening action supporting mechanism 26. As a result, according to the specifications of the opening section device 11, the opening action supporting mechanism 26 can be installed in a plurality of ways, or it becomes possible to select the presence or absence of the opening action supporting mechanism 26 using the same operation mechanism 24 or the same interlocking member 32. That enables achieving a high degree of general versatility.
  • the kicking member 48 is positioned in the housing position at which the roller 69 is retracted inside the vertical stile 12d.
  • the flank face 58b of the driving member 58 is positioned on the upper side of the driving pin 60.
  • the operation handle 29 is turned in the closing direction from the 180° position.
  • the interlocking member 32 moves down and the driving member 58 too moves down accompanying the interlocking member 32, and the flank face 58b makes sliding contact with the driving pin 60.
  • the flank face 58b gets subjected to the pressing force from the driving pin 60, and the driving member 58 moves in the direction away from the driving pin 60 against the biasing force of the torsion coil spring 84 (see FIG. 8(A) ).
  • the driving member 58 not only includes a clutch structure for connecting the interlocking member 32 and the opening action supporting mechanism 26 at the time of turning the operation handle 29 in the opening direction, but also contains a unidirectional transmission structure for maintaining the disconnected state at the time of turning the operation handle 29 in the closing direction where the downward movement of the interlocking member 32 is not transmitted to the opening action supporting mechanism 26 due to the movement of the driving member 58 in the direction away from the driving pin 60 by the pressing force of the driving pin 60.
  • the driving member 58 does not interfere with the turning of the operation handle 29 in the closing direction, and a smooth handle operation can be performed.
  • the drawing member 42 moves down during the movement of the operation handle 29 from the 180° position toward the closing direction.
  • the drawing piece 42a of the drawing member 42 starts getting hooked against the head portion 44a of the lock pin 44 at a position such as the 96° position that is just before the 90° position illustrated in FIG. 8(A) . That is, the locking action of the lock mechanism 22 starts.
  • the head portion 44a of the lock pin 44 moves along the tilt of the drawing piece 42a, the sliding door 12 is gradually drawn in the direction approaching the vertical frame 14d due to the lock pin 44.
  • the opening action supporting mechanism 26 does not operate. For that reason, a defect in which the sliding door 12 is kicked during the locking of the lock mechanism 22 is prevented from occurring.
  • the operation handle 29 moves within the turning range from the 0° position to the 180° position. Hence, the operation handle 29 never overhangs from the contour range of the sliding door 12. For that reason, the operation handle 29 never interferes with the frame member 14.
  • the interlocking member 32 is configured by linking the linking member 38, the interlocking lever 40, and the coupling member 41.
  • the interlocking member 32 can be configured using a single component or two components.
  • the interlocking member 32 when the interlocking member 32 is configured using the combination of the linking member 38 pertaining to the operation mechanism 24; the interlocking lever 40 pertaining to the lock mechanism 22; and the coupling member 41 pertaining to the opening action supporting mechanism 26 and the clutch mechanism 28; for example, in the case of implementing the interlocking member 32 in an opening section device not requiring the opening action supporting mechanism 26, it becomes easily possible to omit the opening action supporting mechanism 26 and the clutch mechanism 28, thereby enabling achieving a high degree of general versatility.
  • the configuration is explained in which the interlocking member 32 moves up when the operation handle 29 is turned in the opening direction and moves down when the operation handle 29 is turned in the closing direction.
  • the up-and-down relationship can be reversed.
  • the configuration is explained in which the lock mechanism 22 and the opening action supporting mechanism 26 can be simultaneously operated.
  • the opening action supporting mechanism 26 and the lock mechanism 22 can be configured to be separately operable; or the lock mechanism 22 can be omitted.
  • the operation mechanism 24 can be electric equipment having a motor, or can be a hand operating device in which the interlocking member 32 is moved up and down using some other component such as a lifting lever instead of using the operation handle 29.
  • the opening section device 11 is a fitting having an inner sash structure in which the sliding door 12 slides at the room side of the fixed door 16.
  • the opening section device 11 can have an outer sash structure in which the sliding door 12 slides at the outdoor side of the fixed door 16. Even when the external sash structure is adapted, the operation handle 29 is retained at the 180° position after the end of the actions of the opening action supporting mechanism 26. Hence, when the sliding door 12 is completely open, the operation handle 29 is prevented from interfering with the meeting stile (the vertical stile 16d) of the fixed door 16, thereby enabling achieving maximization of the opening dimensions of the sliding door 12.
  • the fitting is configured with the sliding door 12 of the single sliding type as the door body whose opening action is supported by the opening action supporting device 10.
  • the opening section device 11 can be used also in doors and windows having various sliding structures, such as in a double sliding door in which, for example, two sliding doors 12 are disposed in a double-slidable manner, or in a window disposed at a position from which people enter and exit.
  • the door body whose opening action is supported by the opening action supporting mechanism 26 can be, for example, a door or a horizontal pivoted window that is different than a sliding door.
  • the opening action supporting mechanism 26 can be disposed in a horizontal stile instead of a vertical stile.
  • the opening action supporting device 10 can be disposed with respect to the face bar or the aggregate constituting the door body.
